For appliances that support hardware single instancing of data (for example, Centera) you can enable the option to write the data in a single instancing format.
Note
This is hardware deduplication and should not be confused with Commvault's Deduplication feature. Commvault's Deduplication is not supported when this option is enabled.
The following Agents support this feature:
|
Agent |
What is Deduplicated |
|---|---|
|
Windows File System iDataAgent |
Files (Metadata that is associated with files is not deduplicated.)* |
|
Unix File System iDataAgents |
Files |
|
Macintosh File System iDataAgent |
Files |
|
Exchange Mailbox iDataAgent |
Attachments |
|
SharePoint Document iDataAgent |
Documents (Meta-data associated with documents are not deduplicated.)* |
*Metadata includes Access Control Lists (ACLs) and any additional streams associated with the files.
The following operations are not supported:
-
Data Multiplexing to a deduplicated library.
-
Auxiliary copy (including Inline Copy) of multiplexed data to a deduplicated library.
Note
Once you have valid data in the library, you will not be able to change the deduplication status for the library, whether the option is enabled or not.
Procedure
-
From the CommCell Browser, expand to Policies | Storage Resources | Libraries.
-
Right-click the appropriate library, and then click Properties.
-
Click the Mount Paths tab.
Mount paths that are enabled with hardware single instancing must be less than 100 characters long.
-
Click the Disks within this library support Hardware Single Instancing check box.
A message appears that tells you that once there is valid data associated with the selected library, you will not be able to select or clear this option.
Note
When this option is selected, the underlying storage is able to do single instancing on files, where the same file content is written multiple times. The data is not written in a container format, where multiple files are combined together into a chunk.
-
Click Yes and click OK.
